Highly Efficient Removal of Organic Pollutants with HCO3−-Enhanced Ru(III)/NaClO Process

International Journal of Molecular Sciences, Год журнала: 2025, Номер 26(2), С. 677 - 677

Опубликована: Янв. 15, 2025

The design of efficient advanced oxidation processes (AOPs) in the presence bicarbonate has long attracted considerable attention field environmental catalysis. In this study, sodium (NaHCO3) as one most abundant substances actual water, was introduced to a NaClO/Ru(III) system enhance removal acid orange 7(AO7). NaHCO3 could significantly improve efficiency Ru(III)/NaClO process HCO3− at pH range 6.9–10.0. Ru(V)=O identified dominant reactive species involved degradation pollutants NaHCO3/NaClO/Ru(III) system. interacts with Ru(III) generate Ru(III)-HCO3−, which enhances activation performance under neutral or alkaline conditions. AO7 enhanced increasing concentration, and rate constant increased more than 2-fold 4-fold concentrations from 0 100 mM 6.9 8.5. This study proposed novel strategy environmentally friendly inorganic ligands highlights its potential applications pollutants.

Enhanced heterogeneous Electro-Fenton catalysis using CNT/MoS2/FeCo-LDH cathode membranes for efficient phenol removal from wastewater

International Journal of Electrochemical Science, Год журнала: 2024, Номер 19(7), С. 100633 - 100633

Опубликована: Май 9, 2024

Herein, we innovatively crafted a novel CNT/MoS2/FeCo-LDH cathode membrane using facile vacuum filtration method. Benefiting from the unique heterostructure between FeCo-LDH and MoS2, prepared membranes catalyzed production of high-concentration H2O2 (7.59 mg/L) at low current density 1.50 mA/cm2. The peak degradation efficiency phenol (98.80%) was reached in only 60 minutes. Under optimized operating conditions, removal rate remained above 80.00% within wide pH range (3.0-9.0), demonstrating excellent adaptability. synergistic incorporation Mo, Fe, Co ions facilitated additional chemical reaction pathways for Fenton-like reactions, thereby significantly enhancing hydrogen peroxide production. Notably, our approach exhibited moderate total organic carbon efficiency, even actual pretreatment coking wastewater, presenting promising strategy addressing recalcitrant industrial wastewater.
